The next of the Big Four liners to be launched was was Cedric, which went down the slipways in 1903. She departed Liverpool for New York on her maiden voyage on February 11th, 1903, and like her sister before her, she was almost completely assigned to operating the Liverpool - New York route, often referred to as the 'Atlantic Ferry'. She was just slightly heavier than her older sister Celtic II , weighing in at 21,035 tons.

On March 15th, 1905, Cedric was hit by two huge waves whilst battling through a storm in the North Atlantic, which caused some slight structural damage, but she battled on, and made her way safely home.

When Titanic sank in 1912, Cedric was in New York. But her departure was postponed until Carpathia arrived, therefore allowing any of the surviving Titanic passengers to travel back to England aboard Cedric. Some of the crew of Titanic who weren't required to give evidence at the United States Enquiry also used Cedric to get back to English shores.

Again, like her sister before her, Cedric was utilised during the outbreak of war in 1914, firstly as an armed merchant cruiser, and then spending some time as a troop carrier. During this period she rammed and sank the Canadian Pacific Line's Montreal close-to Liverpool on January 29th, 1918.

At the end of the war, in 1918, Cedric returned to service, and the following year underwent a refit.

Cedric was withdrawn from service in 1931, and scrapped the following year.
